Jan Aushadhi — cost of product is inadequate

Address:

Ghaziabad, Uttar Pradesh

Respected sir/madam,
Medicines provided by the store-'jan aushadhi medical store' are inappropriate. Cost of medicine is different when purchased without bill. The owner of the store provide different rates to different customers. A tablet namely cilnep-t when i first purchased it was of rs.40. Then second time it was of rs.30 and thirdly they sold me the same tablrt at rs.50. This is againstthe law of consumer protection act.
Kindly, take a strict action against this.
Regards,
Avanesh kumar
